Description

The FM25V01 is a 128-kilobit nonvolatile memory

employing an advanced ferroelectric process. A

ferroelectric random access memory or F-RAM is

nonvolatile and performs reads and writes like a

RAM. It provides reliable data retention for 10 years

while eliminating the complexities, overhead, and

system level reliability problems caused by Serial

Flash and other nonvolatile memories.

Unlike Serial Flash, the FM25V01 performs write

operations at bus speed. No write delays are incurred.

Data is written to the memory array immediately

after it has been transferred to the device. The next

bus cycle may commence without the need for data

polling.

The

product

offers

very

high

write

endurance, orders of magnitude more endurance than

Serial Flash. Also, F-RAM exhibits lower power

consumption than Serial Flash.

These capabilities make the FM25V01 ideal for

nonvolatile memory applications requiring frequent

or rapid writes or low power operation. Examples

range from data collection, where the number of

write cycles may be critical, to demanding industrial

controls where the long write time of Serial Flash can

cause data loss.

The FM25V01 provides substantial benefits to users

of Serial Flash as a hardware drop-in replacement.

The device uses the high-speed SPI bus, which

enhances the high-speed write capability of F-RAM

technology. The device incorporates a read-only

Device ID that allows the host to determine the

manufacturer, product density, and product revision.

The

device

is

guaranteed

over

an

industrial

temperature range of -40°C to +85°C.
